GREENFIELD – Brothers Kenneth and Patrick Jean-Babets were sentenced to jail Wednesday for their attack on two police officers in the Sunderland Police Station.

Their sentencing came almost three weeks after a Franklin County jury convicted the brothers of two counts each of assault and battery on a police officer and threatening to commit a crime. Kenneth and Patrick Jean-Babets arrived at the police station on Feb. 21 of this year, shortly after a third brother, Steven Jean-Babets, was arrested for marijuana possession and a traffic violation. Police Chief Jeffrey Gilbert testified at their trail that Kenneth and Patrick stormed the room after Gilbert opened the door, attacking him and police officer Gary Sibilia.

Gilbert said Kenneth Jean-Babets brandished a knife at him during the attack, but Gilbert was able to knock it to the floor. The jury found Jean-Babets not guilty of assault with intent to murder, however. The officers subdued and arrested the brothers after a brief struggle.

Franklin Superior Court Judge Richard Carey sentenced Kenneth Jean-Babets, 26, to 2½ years in jail followed by three years of probation. Patrick Jean-Babets, 24, was ordered to serve a one-year jail sentence followed by three years probation. As conditions of their probation, the brothers must remain drug and alcohol free, submit to random screens, undergo mental health counseling and have no contact with police officers.

Kenneth, Patrick and Steven Jean-Babets, along with a fourth brother, are biological siblings who were adopted by David Jean and Donald Babets. The couple had previously sued the state over its foster care regulation, claiming they discriminated against same-sex parents. The suit paved the way for gay couples to adopt in Massachusetts.
